To ctZZwzom/t may concern.` i s Be it known that l, FREDERICK CONRADRoBiin'rsoN, a citizen or theUnited States,

and a resident ot Spokane, inthe county oi Spokane and State oillfashington, have in-w vented certain new and useful Improvements inlflorseshoes, oit which the .following is a specification. 1 i

The present invention relates generally to horseshoes, and moreparticularly .to a

cushioned horseshoe oif composite structure.y

yThe object ot the invention is to provide a composite horseshoe of thischaracter` in which the force oi impact and the tearing and majorabrasive `iorces acting along' the shoe are received by a`metallicelement and `thereby prevented from breaking down the structureof the cushioning element, and in which the cushioning element ismosthighly effective to absorb the stresses set up bv the forces acting uponthe metallic clement and to `receive and absorb the forces not eiiectiveto deteriorate the cushioning element.

Another object of the invention is to pro vide a horseshoe ol thischaracter of simple,

` durable and lightweight construction, reli-` able and efficient inpractice, and easy and f inexpensive to manufacture. Other ob]ects andadvantages residein the certain novel features of construction, ar-

rangement and coinbinationot parts which willbe hereinafter more fullydescribed and particularly pointed out in the appended claims, referencebeing had to `the accouv panying drawings :forming part olf' thisspecification, and in whichp Figure 1 is an elevational view oi" treadsurface of the shoe;

Referring tothe drawings, it will beseen that the'invention in all oicits embodiments f contemplatesa cushioning element indicated enerallyTat @anda metallic element indicated generally atM. n

in the einbod'ment of the invention shown in Figs. 1 to `6,thecushioningelementconiprises a bodjy'oi1 cushioning material, ,suchas vulcanizedrubber, and includes a sheet-like portion 10 arranged to bear againstthe hoot oit the horse. The body also includes a sheet like portionwhich constitutes the inner portion oif the tread surface oil' the shoe,and an intermediate portion 1,2 integral with the between the portienslOand lland abut vthe portion 12 of the cushioning i element. The

plate 13 is vprovided. with an integra-l margip portions 10 and llandconnecting the same. i

c canizedrubber oi? the body of the shoe tolie "ik nal flange 14; whichextends entirely around 1 the outer marginal edge of the shoe and alsoaround the heel of the shoe, as indicated at 15 in Figs. 1 and 2. Theouter surface 14? oi' the flange is arranged` to `constitute the i outerinarginal portion of the tread` surface ot the shoe. i y The metallicplate 13 is `provided with'a `plurality7 ot hey openings' 16 `throughwhich 'the vulcanized rubberextends to more positively associate themetallicand cushioning io o ' rubber arethus in general cao-planar andtogether' make up the tread surface of the-shoe.l

elements. The shoe is also provided with nail holes 17 which, as clearlyshown in the drawings, extend through the flange 14 and theunderlyingportion 1 of the rubber.

The surface ofthe rubberI constituting a portion oli'the tread surfaceis suitably formed to prevent slipping and lor this purpose is'providedwith a plurality of vacuum or suction cups 18 and a plurality ofserrations or similar devices 19.` rl-vhe planes of the highest pointsoif the anti-'slipping de- `-vices however, areall coincident'or below,v

preferably Ycia-incident, with thel tread surface"14aof the flange 14.The tread surface off the flange and the tread surface ofthe ln use, thetread suriace'l4a of the fia-nge 14 receives the impact Land the majorforces incident to traction, as this surface 14a`extends entirely aroundthe outer marginal 'ledge-of the shoe. T hestressesset up in thev flange14 andthe metallic plate 13 of which it forms a parta'renot,however,com1nunicated'tov the hoof of the horse, but are ab sorbed bythe cushioning material, mainly by the Aportion l()4 thereoi whichunderlies and is interposed between the flange 14 and i its plate 13,and the hoot.` Although the surface 14a o l' the metallic elementreceives the force of impact and `the major abrasive and other forcesincident to traction, the tread surface of the portion 111 ofthe-vulcanized `rubber comes yinto action `almost simultaneously with orat least immediately y after the impact andisellective to enhance thetraction and thereby prevent slipping and to receive and absorb theminor forces -actingupon the shoe. The portion 11 of the cushioningmaterial is strengthened and supported inits function bythe metallic y"plate 13, and the cushioning action of the portion 11issupplementedby asimilar actionof'the portions 10 and 12. i

y lt vis to be noted that although the metallic element is lirinlyei'nbedded in the vulcanized rubber constituting the body und ispositively associated therewith by virtue ol 'the Yextension of therubber through the key openings, the lflange 14, fin additiomisoliective at the ltoe and heelandpentirely around tfhe shoe to preventdisassociation of the rubf loer or of any portion thereof 'from therne-` tallic element, functioning 1n this respect as alretaining ring topreventl tearing, split- *ting7 or similar :breakdown ofthe cushioningelement which would otherwise be incident to traction. f

In the embodiment of the invention shown in'Figs. 7, -8 and 9, thecushioning element comprises a body of vulcanized rubber, and

includesa sheet-like portion 20 which may be'ar directly against thehoof or which may loe-provided with a covering 21 oi tough fabric. Thebody also includes a portion 22 ing action of'this embodiment ofthe-'invenwhich, as before, constitutes the inner portion of the treadsurface of the shoe. A pad Jforms an integral part or' the cushioningelement and extends entirely across-the'heel ei theshoe andcentrallythereol, as'clearly shown in F 7., i i n A metallic element 24is provided, and consists oi a plate of horseshoe form, embedded in thevulcanized rubber of the shoe and lies between #the portions 2O and 22thereof.A The plate is provided with anintegral marginal `flange A25.which extends entirely around the outer-'marginal'edge ofthe shoe, asshewn'in Fig. 'i'. rrlhe outersurface of the i'iange thus constitutesthe outer inarginaly portion of the tread surface of the;

shoe. The metallic plate vis provided with a plurality 'of key openingsv26threiigh which the vulcanized rubber oi the cushioning elementextends to positively associate thejrnetallic and cushioning elements.fllhe -shoe'is also provided with nailiholes 2'? which extend throughthe flangel and thelunderlying portion of the cushioning element.

The surfaces of the rubber and ofthe metal constitute thetreachand are`suitably' vl'orinedtor prevent slipping, andthe highest points of therubber and of the metallic elevment lie in the same plane for else thehighest points o1 the surface ofthe rubber lie fbelow the plane of lthehighest points or' thesu-rtace shown in Figs. i', 8 land '9, but thisierniov my invention may be also embedded inshoes el?` the type shown inFigs. Ito! Gf. This torni oi ytheI invention includes av metallicelement and :L cushion-lng element C, the cushioning element consistingoi vulcanized rubber and the meta-liu?y element being fonstjitu'ted oitany suitable metal. arly shown in the drawiiig, the cusl-iionifhgelement is formed in general of two sections 28 and 29, which-*areformed by splitting the tipping of the shoe, as at 30. lt isfobviousthat the sections 2S andg29 lmay be liexed to varythe sizeof the vshoe`and that the metallic elements B1 'oi' various lsizes may, after thesections have been suitably'rleiied,' be slipped over thesectionstoembrace and retain the same in position. NVhen the shoe is then securedtothehoof of Athe horse by the nails` whichextend through Vthe-nailholes' of the metallic element and of the ,cushioning element the partsare positively maintained in assembled position, The cushion- A tion isin all respects similar tok that of the` `ifi-lirica e other embodimentsoi' the invention, as hereinabove described. i

ln Figs. i3 to `19 inclusive Will be seen a nlodiiied torni oi' theinvention in which `a horseshoe 32 is disclosed `made in substantiallythe conventional forni, but designed to receive the cushioning member33, which may be made of rubber or other material,

said cushioning member havinga thick inner section and a comparativelythin flange or `outer section 35 adapted to lit llatvvise against theinner surface of the shoe 32. A pad 86 is also provided `formed with aheel 37 and a flat body 38 adaptedito lit beneath the cushioning member33 and to entirely cover the horses hoof when in use. This constructionmaybe made completely of rubber, or it desired may be made from canvasor other stiiiening` material arranged therein, particularly in the heelmember 37. After the parte have allbeen assembledas shown in lfigs.` 17and 19` the ordinary horseshoe nails are forced through the usual`openings 39 through tlange 35 and part oi' the body 38 of padand vtronithence into the horses hooi. The usual nails in this manner not onlyhold the completed shoe in place on the horses :toot but hold Athe*`various parts i'irmly together so they will act simultaneously and in aproper manner. ltivill be noted from Fig. 18 that part of the rubbercushion engages the,` ground, and the horseshoe S2 engages the groundadjacent the cushion While the horseshoe is continually cushioned by theflange 35 and part ot the pad l claim: y
